The SBS1U is a
pressure die cast aluminium sensor housing (IP65) with an
integrated sensor for highly sensitive, uniaxial acceleration or
inclination measurements.
As well as the sensor, the housing contains a signal conditioner
with 0...5V output and a separate, highly stable voltage supply.
Furthermore, the signal conditioner includes active low pass
filters for suppression of interference signals and transient
suppression for EMC guarantee. Interference signals caused by
unwanted ground currents are eliminated by electrically isolating
sensor and signal conditioner from the housing. The terminals
provide either two mutually inverse asymmetric 0...5V or one
symmetrical ±5V output voltages.
The compact metal cable gland and small housing size in
combination with the max.6-wire connection enable the use of this
high quality measuring system in harsh operating conditions.

Application

The SBS1U is
suitable for applications requiring extremely precise inclination
or acceleration measurements under harsh circumstances and
returning of an analog signal output. Typical areas of successful
application include stability monitoring of buildings and
machinery and inclination monitoring on bridges, dams, towers,
tunnels, slopes and structures in danger of collapse or
earthquakes.
